Camera Exposure and Settings

A photograph’s exposure is how light or dark a picture can be captured. Taking a picture can be a lot like catching rain in a bucket. We can take control the width of the bucket, how long you collect the rain, and how much rain you collect (which could be represents aperture, shutter speed, and the ISO). The aperture controls the area in which the light can enter the camera to take a picture (depth of field meaning the distance). The shutter speed controls the duration of the exposure (motion blur). Lastly the ISO speed controls sensitivity of the camera’s sensor to the given amount of light (image noise meaning the sound waves in a way). For the aperture it’s referred to f-stop values (as this value halves the light collecting area quadruples (4x). For the shutter speed you increase the speed if the focus photo come out a blur. Also in the night time or where there’s not enough light make the speed slower. For the ISO speed a lower ISO speed is more desirable in picture taking because it does not come out blurry. An ISO speed would cause the picture to become blurry. There are different modes on the camera where it gives more priority to the 3 modes (aperture, shutter speed, and the ISO). The symbols mean: auto is represent by a green square, program with a “P”, aperture priority is represented by “AV”, shutter priority is represented by “TV”, manual is represented by an “M”, and lastly bulb is represented by a “B”. AV, TV, and M are known as the creative modes. These settings are important to taking a picture because it means the quality of picture you are going to take.
